Detailed explanation-1: -Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. He suggested that Pangaea broke up long ago and that the continents then moved to their current positions. He called his hypothesis continental drift.

Detailed explanation-2: -In 1912 Alfred Wegener (1880-1930) noticed the same thing and proposed that the continents were once compressed into a single protocontinent which he called Pangaea (meaning “all lands"), and over time they have drifted apart into their current distribution.

Detailed explanation-3: -In 1912, German scientist Alfred Wegener proposed that Earth’s continents once formed a single, giant landmass, called Pangaea. Over millions of years, Pangaea slowly broke apart, eventually forming the continents as they are today. The video below shows how this happened over one billion years.

Detailed explanation-4: -Pangea, the supercontinent For Wegener this was only possible if the current continents were once concentrated around the equator forming a supercontinent, which broke apart some 200 million years ago and which he called Pangaea.

Detailed explanation-5: -Pangea’s existence was first proposed in 1912 by German meteorologist Alfred Wegener as a part of his theory of continental drift. Its name is derived from the Greek pangaia, meaning “all the Earth.”
